MOLD FOR CASTING POURED-CONCRETE BLOCKS.

Specification of Letters Patent.

Patented Feb. 13, 1917.

Application filed. July 27, 1916. Serial No. 111,678.

' consisting of sections or members which can be readily andquicklyassembled into a series or plurality of molding spaces, and removablysecured together by any suitable or convenient means.

The main object of the invention is to construct .a simple, inexpensive,durable and thoroughly eflicient device in the method of majcing pouredconcrete blocks or bricks on enc.

Another object of the invention is to provide molds constructed entirelyfrom suitable sheets of metal which can be rapidly assembled, and soconstructed that the entire mold can be removed before the block orbrick is strong enough to handle, said molds requiring but little floorspace and no bottom other than a suitable platform.

A further object of the invention is to provide molds for pouredconcrete bricks or blocks in sections, which may be connect ed togetherin series, and in which the partitions separating the sections areremovably connected to the side members of eachsection and soconstructed that a handle is formed by an integral extension at eachside or end thereof, said partition plates always resting flush andlevel with the upper edge of each mold.

A still further object of the invention is to provide in connectionwithmy improved mold an attachment forming a partition which is employedto apply a facing of clifferent or richer material than thatconstitilting the body of the block, said attachpended hereto, it beingunderstood that slight changes 111 the form, proportions, and

minor details of the construction may be resorted to without departingfrom the spirit or sacrificing any of the advantages of the invention. VIn the accompanying drawings it will be seen that Figure 1, is a planview of the improved device embodying my invention.

Fig. 2, is a side elevation of the same, and

' Fig. 3, is a perspective view showing the members of each mold beforethe parts are assembled or joined together.

Similar numerals of reference are employed to designate correspondingparts throughout the several figures of the drawmgs.

.In the embodiment of this invention as illustrated and which shows apreferred construction, the numerals 1 designate the side member of eachmold box, said side members being preferably formed of flexible sheetsteel and provided with the inwardly projecting portions 2 at thecentral portion thereof and an outwardly projecting longitudinal flange3'at each side;

The partition plates for separating one mold from the other consist eachof a flat metal plate 4% having integral extensions bent oppositely atright angles to the plate at its top and bottom portion at each sidethereof, said extensions on each side of each plate being arranged oneabove the other and projecting in opposite directions in verticalalinement, the top and bottom right angle extensions 5 at the right handside of the plate projecting in opposite directions, and theintermediate right angle extensions 6 beingpositioned in a directionopposite to the extensions 5, while the corresponding extensions on theleft hand, or opposite side of the plate project in a direction oppositeto those on the right hand side, whereby in assembling each mold a topand intermediate extension 5 and 6, and a bottom and intermediateextension 5 and 6 will contact with the outer edge or surface of theflange 3 of each side member and hold said member in its proper positionand alinement, and each side of each of said plates 4t is provided witha lateral extension 7 which projects beyond the mold proper, therebyforming a handle for manipulating the plates and readily removing themfrom the molds, as clearly shown in the drawings.

When it is desired to apply a facing of different or richer materialthan that from which the body of the block is formed, I employ a flatmetal. plate 8, provided at each side thereof with an integral flange 9,at right angle to the body of the plate, the outer or terminal edge ofeach flange resting in contact with the inwardly inclined wall of eachside member 1., thereby forming a suitable space'between the plate 8,and partition plate 4i, to receive the fac ing material. Each of theplates 8 are made longer than the mold members so that it projects abovethe top of the molds thereby forming an extension 10, constituting ahandle therefor, by which the said plate 8 may be manipulated inplacing-it within and removing it from the mold.

Itv will be understood that the concrete for the body of the block andalso the facing material is-so mixed that it will pour freely, hencewhen the plate 8 is withdrawn, which is immediately after the materialfor forming the body of the block and the facing is poured, the materialthen being in a plastic condition permits the body and facing to readilyunite and adhere together thus forming a solid and integral block.

From the foregoing, it will be readily obvious that the molds require nobottom other than a suitable platform, and that the mold is soconstructed that it can be rapidly assembled and the entire mold can bequickly removed before the block is strong enough to handle.

It will also be obvious that any suitable means may be utilized forclamping or holding a series of the molds together, and while I haveshown a series of four molds any suitable number of the molds may beconnected together, the partition plates t separating one mold from the.other.

Having thus described my invention what I claim and desire to secure byLetters Patent is: i

1. A mold for concrete block's comprising two detached side members,each of said side members having an inwardly projecting central portionextending throughout its height and an outwardly integral right angleprojecting flange at each end thereof, and a plate at each end of themold provided with anintegral right angle oppositely disposed extensionat the top and bottom of each side, and an intermediate oppositelydisposed right angle extension at the top side members having aninwardly project-1;

ing central portion extending throughout its height and an outwardlyintegral right angle pro ect-mg flange at each endthereof,

a detached partitionplate at each end hav ing an integ'al right angleoppositelyidisposed extensionat the top. and bottom of each side; anintermediate oppositely positioned right angle extension at the topandbottom portion at each side thereof, saidtop and intermediate extensionsbeing positioned opposite each other in vertical alinement andadapted-to contact with the outer edge of the outwardly projectingflangeof each of theside members, and said partition plate having alateral extensionformed on each side between and projecting beyond thesaid rightangle extension to form a -handle.

8. Amold for concrete blocks comprising two detached side members, eachside member having an outwardly projecting flange at each end thereof,and an inwardly projecting central portion extending throughout itsheight, a partition plate provided with top and bottom and intermediateright angle oppositely disposed integral extensions at each side thereofadapted to contact with the outer edge of the projecting flange of eachside member, in combination with a plate having right angle integralflanges at each side thereof adapted to contact with the inner face ofthe inclined walls of each of the side members, and having an extensionprojecting beyond the top of the mold to form a handle therefor.
